The present disclosure relates to portable electronic devices, and inparticular to portable electronic devices having a slidable upperhousing and lower housing movable between an open position and a closedposition, and including a plurality of position sensors for detectingthe position of the portable electronic device and whether the portableelectronic device is in a holster.

BACKGROUND

Electronic devices, including portable electronic devices, have gainedwidespread use and may provide a variety of functions including, forexample, telephonic, electronic text messaging and other personalinformation manager (PIM) application functions. Portable electronicdevices can include several types of devices including mobile stationssuch as simple cellular phones, smart phones, Personal DigitalAssistants (PDAs), tablets and laptop computers.

Devices such as PDAs or smart phones are generally intended for handhelduse and ease of portability. Smaller devices are generally desirable forportability. In some cases, such devices may be touch sensitive devices.For example, touch-sensitive devices constructed of a display, such as aliquid crystal display (LCD), with a touch-sensitive overlay may beuseful on some handheld devices as such handheld devices tend to besmall and are therefore limited in space available for user input andoutput devices. Further, in some cases the screen content on thetouch-sensitive devices can be modified depending on the functions andoperations being performed. In other examples, some personal electronicdevices may not have touch sensitive displays.

It will be appreciated that for simplicity and clarity of illustration,where considered appropriate, reference numerals may be repeated amongthe figures to indicate corresponding or analogous elements. Inaddition, numerous specific details are set forth in order to provide athorough understanding of the embodiments described herein. However, itwill be understood by those of ordinary skill in the art that theembodiments described herein may be practiced without these specificdetails. In other instances, well-known methods, procedures andcomponents have not been described in detail so as not to obscure theexample embodiments described herein. The description is not to beconsidered as limited to the scope of the example embodiments describedherein.

FIG. 1 shows a simplified block diagram of components including internalcomponents of a portable electronic device 100 according to someembodiments.

The portable electronic device 100 includes multiple components such asa processor 102 that controls the operations of the portable electronicdevice 100. Communication functions, including data communications,voice communications, or both, may be performed through a communicationsubsystem 104. Data received by the portable electronic device 100 maybe decompressed and decrypted by a decoder 106. The communicationsubsystem 104 may receives messages from and send messages to a wirelessnetwork 150.

Generally, the wireless network 150 may be any type of wireless network,including, but not limited to, data-centric wireless networks,voice-centric wireless networks, and dual-mode networks that supportboth voice and data communications over the same physical base stations.

The portable electronic device 100 may be a battery-powered device andas shown may include a battery interface 142 for receiving one or morerechargeable batteries 144.

The processor 102 may also interact with additional subsystems such as aRandom Access Memory (RAM) 108, a flash memory 110, a display 112 with atouch-sensitive overlay 114 connected to an electronic controller 116that together may comprise a touch-sensitive display 118, an actuatorassembly 120, one or more optional force sensors 122, an auxiliaryinput/output (I/O) subsystem 124, a data port 126, a speaker 128, amicrophone 130, a short-range communications subsystem 132 and otherdevice subsystems 134.

In some embodiments, user-interaction with the graphical user interfacemay be performed through the touch-sensitive overlay 114. The processor102 may interact with the touch-sensitive overlay 114 via the electroniccontroller 116. Information, such as text, characters, symbols, images,icons, and other items that may be displayed or rendered on a portableelectronic device, may be displayed on the touch-sensitive display 118via the processor 102.

The processor 102 may also interact with an accelerometer 136 as shownin FIG. 1. In some embodiments, the accelerometer 136 may include acantilever beam with a proof mass and suitable deflection sensingcircuitry. The accelerometer 136 may be utilized for detecting directionof gravitational forces or gravity-induced reaction forces.

To identify a subscriber for network access according to the presentembodiment, the portable electronic device 100 may use a SubscriberIdentity Module or a Removable User Identity Module (SIM/RUIM) card 138inserted into a SIM/RUIM interface 140 for communication with a network(such as the wireless network 150). Alternatively, user identificationinformation may be programmed into the flash memory 110.

The portable electronic device 100 may also include an operating system146 and software components 148 that may be executed by the processor102 and which may be stored in a persistent store such as the flashmemory 110. Additional applications may be loaded onto the portableelectronic device 100 through the wireless network 150, the auxiliaryI/O subsystem 124, the data port 126, the short-range communicationssubsystem 132, or any other suitable device subsystem 134.

In use, a received signal such as a text message, an e-mail message, orweb page download may be processed by the communication subsystem 104and input to the processor 102. The processor 102 then processes thereceived signal for output to the display 112 or alternatively to theauxiliary I/O subsystem 124. A subscriber may also compose data items,such as e-mail messages, for example, which may be transmitted over thewireless network 150 through the communication subsystem 104.

For voice communications, the overall operation of the portableelectronic device 100 may be similar. For example, the speaker 128 mayoutput audible information converted from electrical signals, and themicrophone 130 may convert audible information into electrical signalsfor processing.

Turning now to FIGS. 2 to 11, illustrated generally therein is aportable electronic device 200 according to one embodiment. The portableelectronic device 200 generally includes an upper housing 202 (orsliding portion) and a lower housing 204 (or base portion). Generally,the upper housing 202 and lower housing 204 are coupled together and areslidable between a closed position (as shown in FIG. 2) and an openposition (e.g. as shown in FIG. 6). The upper housing 202 generallyincludes a display 206, which could be an LCD display and which may havetouch screen capabilities.

As shown, one or both of the upper housing 202 and lower housing 204 mayinclude one or more input apparatus, such as navigation keys or buttons,a physical or virtual keyboard, a trackpad, trackball, multimedia keys,etc. For example, the upper housing 202 as shown includes an auxiliaryinput device 212. The auxiliary input device may be an opticalnavigation module (e.g. a trackpad) that responds to user interaction,and which may be used for navigating around the display screen 206, toselect objects on the display screen, or for other purposes. In someother embodiments, the auxiliary input device 212 may be a mechanicaldevice that responds to user interaction (e.g. a trackball).

The display 206 and the auxiliary input device 212 may be generallydisposed on a front of the upper housing 202 and exposed for useraccessibility when the portable electronic device 200 is in either ofthe open or closed positions.

The upper housing 202 may also include other input devices, such as adedicated phone application button, a dedicated “disconnect call”button, a home screen button, etc. In various embodiments, one or moreof these input devices may include optical sensors, mechanical buttons,or both.

Turning now to the lower housing 204, the lower housing 204 may includevarious buttons and other controls, such as buttons 208 and 210, andwhich could be used for navigation, to control volume or for otherpurposes.

The lower housing 204 could also include one or more application buttons211 that can be used to automatically launch a particular application onthe portable electronic device (e.g. a camera application, a phoneapplication, etc.). In some embodiments, the button 211 may beconfigurable by a user (e.g. the user may be able to select theparticular application or function that is launched by the button 211).

As shown in FIGS. 2 and 6, the lower housing 204 could also include oneor more input or output ports (e.g. I/O ports), such as a microUSB port214. In some examples, the port 214 may be used for data communicationwith the portable electronic device 200, for charging of a battery (notshown) on the device 200 or for both.

As shown, the lower housing 204 may also include a battery cover 216 forcovering the battery. In some embodiments, the battery cover 216 may beremovable. In other embodiments, the battery cover 216 may bepermanently fixed to the device.

In some embodiments, the lower housing 204 may also include an audiojack 217. The audio jack 217 may be used to couple the portableelectronic device 200 to an accessory such as a speaker, a microphone,or both, for example for use in voice communication.

Turning now to FIGS. 6 to 9 and 11, as shown when the portableelectronic device 200 is in the open position, a keypad 220 is exposedon a lower portion 218 of the lower housing 204. The keypad 220generally includes a plurality of alphanumeric keys 222, which may bepositioned in a plurality of rows and columns. In some embodiments, thekeys 222 may represent the alphabet and may be arranged with a standardkeyboard layout (e.g. QWERTY, QWERTZ, DVORAK, etc.)

As shown in FIGS. 2 to 5, when the portable electronic device 200 is inthe closed position, the keypad 220 is covered by the upper housing 202.This may be beneficial as it may protect the keypad 220 when not in use,and may also inhibit undesired keys from being pressed when the user iscarrying the portable electronic device 200 (e.g. in a pocket). However,in some cases (e.g. when the display 206 is a touchsceen) the user maybe able to perform functions on the portable electronic device 200 whilethe portable electronic device 200 is closed by interacting with thedisplay screen 206 (e.g. using buttons 208, 210, 211, the auxiliaryinput device 212, the display screen 206 itself, etc.).

Alternatively, when the portable electronic device 200 is in the openposition (as shown in FIGS. 6 to 9 and 11), the keypad 220 is exposedfor user accessibility.

In some embodiments, the display 206 may be a touch-sensitive display.The touch-sensitive display may be a capacitive touch-sensitive display,for example, and a user's touch on the touch-sensitive display may bedetermined by determining an X and Y location of the touch, with the Xlocation determined by a signal generated as a result of capacitivecoupling with a touch sensor layer and the Y location determined by thesignal generated as a result of capacitive coupling with another touchsensor layer. Each of the touch-sensor layers may provide a signal to acontroller that represents the respective X and Y touch location values.Thus a feature such as a virtual button or other feature displayed onthe touch-sensitive display may be selected by a mapping of the touchlocation to a feature on the touch-sensitive display.

In some embodiments, the portable electronic device 200 is generallytaller than it is wide. In such embodiments, as the portable electronicdevice 200 moves between the open position and the closed position, theupper housing 202 and lower housing 204 move along a longitudinal axisof the portable electronic device 200.

In some embodiments, the portable electronic device 200 is provided witha holster 234 (see FIG. 14). The portable electronic device 200 may beplaced in the holster 234 when the portable electronic device 200 is notin use, for example, or in other cases such as when the portableelectronic device 200 is being used with a headset. The holster 234 may,for example, help to prevent accidental key-presses of the keypad 220.

Portable electronic devices that are movable between multiple positions(i.e. an open position and a closed position, such as portableelectronic device 200) typically include at least one sensor to detectthe position of the portable electronic device. This tends to allow forenabling or disabling of certain features based on the position of theportable electronic device 200. For example, power may be supplied tosome or all the input devices (i.e. display screen 206, auxiliary inputdevice 212, buttons 208 and 210, application button 211 and the keypad220) when the portable electronic device 200 is in the open position,and power may be cut-off to some or all of the input devices (i.e.keypad 220) when the portable electronic device 200 is in the closedposition.

It is also typically beneficial to know when the portable electronicdevice 200 is in the holster 234. In some embodiments, for example, thismay allow for configurable notification settings. For example, in oneconfiguration the portable electronic device 200 may use a vibrationalert for an incoming call when the portable electronic device 200 is inthe holster 234, and a ring alert for an incoming call when the portableelectronic device 200 is out of the holster 234. Other notificationsettings may also be selected and be dependent on whether the portableelectronic device 200 is in the holster 234 or out of the holster 234.

Furthermore, in some embodiments various features may be disabled whenthe portable electronic device 200 is in the holster 234. This may bebeneficial as it may aid in reducing power consumption.

In some embodiments, the portable electronic device 200 includes twoposition sensors for detecting when the portable electronic device 200is in one of three positions: (1) open position (i.e. the keypad 220 isexposed); (2) closed position (i.e. the keypad 220 is covered); and (3)holster position (i.e. when the portable electronic device 200 is in theholster 234).

Reference is now made to FIGS. 12 to 14, which illustrate schematic sideviews of the portable electronic device 200 having a first positionsensor 230 and a second position sensor 232. Specifically, FIG. 12 is aside view of the portable electronic device 200 in the open position,FIG. 13 is a side view of the portable electronic device 200 in theclosed position, and FIG. 14 is a side view of the portable electronicdevice 200 in the closed position and in the holster 234.

The two position sensors 230 and 232 are typically situated on oppositehousing modules (e.g. one position sensor is situated on the upperhousing 202, and one position sensor is situated on the lower housing204). For example, in the embodiment shown in FIGS. 12 to 14, the firstposition sensor 230 is situated on the upper housing 202 and the secondsensor 232 is situated on the lower housing 204.

The first position sensor 230 and the second position sensor 232cooperate together to detect whether the portable electronic device 200is in the open position, the closed position or the holster position(i.e. the portable electronic device 200 is in the holster 234).Specifically, in some embodiments each position sensor 230 and 232 maybe operable detect the presence of one or more corresponding objects orfields (i.e. magnetic field) and output a sensor output signalindicating the presence or absence of the corresponding objects orfields.

The position sensors 230 and 232 are positioned sufficiently far aparton the upper and lower housings 202 and 204 respectively so thatregardless of the position (open/closed/holster) of the portableelectronic device 200 both sensors 230 and 232 normally cannot betriggered by the same object or field simultaneously. Specifically, theposition sensors 230 and 232 may be positioned sufficiently far apart sothat the objects or fields used to trigger the first position sensor 230will not simultaneously trigger the second position sensor 232, and theobjects or fields used to trigger the second position sensor 232 willnot simultaneously trigger the first position sensor 230.

In some embodiments, the sensor output signal produced by the positionsensors 230 and 232 is a binary signal (i.e. High/Low, On/Off, 1/0,etc.) that indicates either (i) the presence of a corresponding objector field; or (ii) the absence of a corresponding object or field. Inthese embodiments, the positions sensors 230 and 232 can be thought ofas either “ON” (presence of a corresponding object or field), or “OFF”(absence of a corresponding object or field).

In some embodiments the position sensors 230 and 232 are magneticsensors, such as Hall Effect Sensors, that detect the presence of amagnetic field. As is known to those of skill in the art, a Hall EffectSensor is a transducer that varies its output voltage in response tochanges in magnetic field. In the embodiment shown in FIGS. 12 to 14,the first position sensor 230 detects the presence or absence of themagnetic fields produced by a first magnet 236 and a second magnet 238(FIG. 14), and the second position sensor 232 detects the presence orabsence of the magnetic field produced by a third magnet 240. In someembodiments, the first, second and third magnets 236, 238 and 240 aresmall (i.e. less than 5 mm tall).

The first magnet 236 may be positioned in an upper portion 242 of thelower housing 204 so that when the portable electronic device 200 is inthe open position the first magnet 236 aligns with the first positionsensor 230 (see FIG. 12). Accordingly, when the portable electronicdevice 200 is in the open position, the first position sensor 230 maydetect the magnetic field produced by the first magnet 236 and output asensor output signal indicative of the detection. As a result, when theportable electronic device 200 is in the open position, the firstposition sensor 230 is “ON”.

In one embodiment, the first magnet 236 is the magnet inherent in thespeaker of the portable electronic device 200 (i.e. speaker 128).Accordingly, in this embodiment, a separate magnet is not required todetect whether the portable electronic device 200 is in the openposition. This may reduce the cost of the portable electronic device200. This may also reduce the size of the portable electronic device200.

In some embodiments, the third magnet 240 is positioned in a lowerportion 244 of the upper housing 202 so that when the portableelectronic device 200 is in the closed position the third magnet 240aligns with the second position sensor 232 (see FIG. 13). Accordingly,when the portable electronic device 200 is in the closed position, thesecond position sensor 232 will detect the magnetic field produced bythe third magnet 240 and output a sensor signal indicative of thedetection.

The first magnet 236 may be positioned on the upper portion 242 of thelower housing 204 so that when the portable electronic device 200 is inthe closed position there is sufficient distance between the firstmagnet 236 and the first position sensor 230 so that the first positionsensor 230 will not detect the magnetic field produced by the firstmagnet 236. Accordingly, when the portable electronic device 200 is inthe closed position, the first position sensor 230 will be “OFF” and thesecond position sensor 232 will be “ON”.

As shown in FIG. 14, the second magnet 238 is positioned on the holster234 so that when the portable electronic device 200 is in the holsterposition (i.e. the portable electronic device 200 is placed in theholster 234), the second magnet 238 aligns with the first positionsensor 230 (see FIG. 14). Accordingly, when the portable electronicdevice 200 is in the holster position, the first position sensor 230will detect the magnetic field produced by the second magnet 238 andoutput a sensor signal indicative of the detection.

In some embodiments, since generally the portable electronic device 200can typically only be put in the holster 234 when in the closedposition, when the portable electronic device 200 is in the holsterposition, typically both the first position sensor 230 and the secondposition sensor 232 will be “ON”.

In some embodiments, the first position sensor 230 produces a singlesensor output signal that indicates the presence or absence of amagnetic field irrespective of which magnet (i.e. the first magnet 236or the second magnet 238) produced the magnetic field. In otherembodiments, the first position sensor 230 may produce multiple sensoroutput signals, each signal indicating the presence or absence of aspecific magnetic field. For example, the first position sensor 230 mayproduce a first sensor output signal that indicates the presence orabsence of the magnetic field produced by the first magnet 236, and asecond sensor output signal that indicates the presence or absence ofthe magnetic field produced by the second magnet 238.

In one embodiment, the first position sensor 230 is a polarity-dependentmagnetic sensor that produces two sensor output signals. The firstsensor output signal indicates the presence or absence of an N-polemagnetic field, and the second sensor output signal indicates thepresence or absence of an S-pole magnetic field. In this embodiment, thefirst position sensor 230 is capable of distinguishing an N-polemagnetic field produced by one magnet (i.e. the first magnet 236) froman S-pole magnetic field produced by another magnet (i.e. the secondmagnet 238). Accordingly, if one of the first and second magnets 236 and238 produces an N-pole magnetic field and the other produces an S-polemagnetic field, the first position sensor 230 can distinguish betweenthe magnetic field produced by the first magnet 236 and the magneticfield produced by the second magnet 238.

In another embodiment, the first position sensor 230 may include aplurality of dies with different magnetic field strength triggeringpoints in a single package. For example, if the first magnet 236produces a magnetic field of strength A, and the second magnet 238produces a magnetic field of strength B, the first position sensor 230may be provided with two dies. The first die may trigger above magneticfield strength A, and the second die may trigger above magnetic fieldstrength B. It may then be possible to determine which of the twomagnets (the first magnet 236 or the second magnet 238) triggered thefirst position sensor 230 based on which of the two dies was triggered.

Although the position sensors 230 and 232 have been described above asbeing magnetic sensors, it will be evident to a person of skill in theart that other types of sensors may be used. For example, in otherembodiments, the positions sensors 230 and 232 may be proximity sensors.However, if proximity sensors are used, objects, such as a user's hand,may interfere with the proximity sensor's ability to accurately detectthe position of the portable electronic device.

In other embodiments the position sensors 230 and 232 may be mechanicalsensors, such as a mechanical switch.

In some embodiments, the portable electronic device 200 may also includea state determiner (not shown) that receives the sensor output signalsfrom the position sensors 230 and 232 and determines the position of theportable electronic device 200 based on the sensor outputs signals. Forexample, in the embodiment shown in FIGS. 12 to 14, the state determinermay determine that (i) the portable electronic device 200 is in the openposition when the first position sensor 230 is “ON” and the secondposition sensor 232 is “OFF; (ii) the portable electronic device 200 isin the closed position when the first position sensor 230 is “OFF”, andthe second position sensor 232 is “ON”; and (iii) the portableelectronic device 200 is in the holster position when the first positionsensor 230 is “ON” and the second position sensor 232 is “ON”.

The state determiner may be implemented in software, hardware, firmwareor any appropriate combination thereof. In one embodiment, the statedeterminer is implemented in software that is executed on the processor(i.e. processor 102) of the portable electronic device 200. In otherembodiments, the state determiner is separate and distinct from theprocessor (i.e. processor 102).

In some embodiments, the processor (i.e. processor 102) may execute oneor more actions based on the position of the portable electronic device200. For example, the processor (i.e. processor 102) may provide powerto one or more input devices (i.e. display screen 206, auxiliary inputdevice 212, buttons 208 and 210, application button 211 and the keypad220) when the portable electronic device 200 is in the open position,and disable or turn off power to at least one of the input devices (i.e.keypad 220) when the portable electronic device 200 is in the closedposition. In some embodiments, all input devices (i.e. display screen206, auxiliary input device 212, buttons 208 and 210, application button211 and the keypad 220) may be disabled when the portable electronicdevice 200 is in the holster position.

In a further example, the processor (i.e. processor 102) may providevisual notification of an incoming call using the display screen 206when the portable electronic device 200 is in the open position or theclosed position, and an audio notification of an incoming call when theportable electronic device 200 is in the holster position. It will beevident to a person of skill in the art that these are exemplary actionsonly and the processor (i.e. processor 102) may be configured to executeother actions based on the position of the portable electronic device200.
